Recently, my license for Cisco VIRL expired and I wanted to test alternatives to have a lab on my laptop. I got used to install the client and the server parts of VIRL on my laptop, to not have to worry about connectivity when I want to do a lab or a demo to a colleague or a customer. With the exceptional opportunities of the different cloud solutions actually, this is probably not the best solution, but it suits me well for a small lab and I’d like to continue…

After doing a lot of Python tutorials and spending time “playing” with Postman and API calls during my journey to network programmability and automation, I wanted to make a concrete example, from zero to a visible result. Since I love photography and my country is full of beautiful but not well-known places, I chose to do the following: Take the complete list of municipalities, towns and villages in my country.

This software is an “all in one” NetFlow collector, database, WebUI software, able to build pretty nice reports. In my opinion, Netflow is one of the absolutely required software to have a good visibility when you operate a network.

The GUI application to use Cisco VIRL, VM Maestro, comes with a basic internal Telnet and SSH client called “Cisco Terminal”. If, like me, you want to use the rock-solid SecureCRT as terminal emulator client, you need to change the the VM Maestro preferences. VM Maestro configuration Open VM Maestro Go to File and open Preferences Under Terminal, open Cisco Terminal Choose: Use external terminal applications Enter the settings : Telnet command: the location of your SecureCRT.exe Depending on your SecureCRT installation, it could be under: C:\Program Files\VanDyke Software\… or…
